The north is part of the Sierras Pampeanas and is characterized by mountain ranges up to 2,500 m high.

San Luis is ideal for travelers who like to stay away from the destinations of mass tourism. The Sierra de San Luis offers a similar landscape to the much better known Sierras de Córdoba, only more pristine and rougher. Numerous reservoirs and mountain rivers invite you to swim in summer. Most of the small towns in the mountain regions, which are interesting for tourists, have hardly been discovered yet, only in Merlo and some places in the vicinity of the provincial capital (especially Trapiche, El Volcán and Potrero de los Funes ) it can get a bit crowded in summer. The climate in Merlo is known throughout Argentina for its high oxygen content.


The variant of Spanish spoken in San Luis is similar to that of Córdoba and seems more sung than Spanish from Buenos Aires. Indigenous languages ​​are all but extinct in the region.


The climate is warm temperate, with hot, relatively humid summers and cool, very dry and sunny winters. In the sierras it can sometimes snow, but it is not enough for winter sports.

Get in[edit]

The central part of San Luis has good road and bus connections to all parts of the country thanks to its location on the important transport axis between Buenos Aires and Santiago de Chile . The two small airports of San Luis and Villa Mercedes offer connections to Buenos Aires.

Get around[edit]


In San Luis you will mainly find natural sights such as the Sierra de Las Quijadas National Park, the Potrero de los Funes reservoir, the gold mining town of Carolina and, above all, the rugged, steep mountain range Sierra de los Comechingones around Merlo. In San Luis and Villa Mercedes you can also visit some historical buildings.


Hiking, mountaineering and paragliding can be found in the area around Merlo. Mountain biking is also possible there, but only for people in good physical condition because of the very steep slopes. In the centrally located Sierra de San Luis, the topography is a little flatter.


A specialty of the province is goat meat, which is served grilled (chivo a las brasas).


San Luis and Villa Mercedes have comparatively active cultural and music scenes, as well as several discos and nightclubs. In summer, the otherwise quiet Merlo comes to life.
